Title: Method of making double walled, tubular, thermal protective cove rings
Inventor: WALLACE VOLNEY
IPC: B29C65/04

Granted: 1989-08-24
Abstract: A process or method for making a unique, double walled, tubular device which is divided into a plurality of substantially vertically extending compartments (42) which are adapted to be filled with water. The double walled, tubular device is made from first and second sheets (11 and 16) of thermoplastic material in which each sheet (11 and 16) has been folded back over itself along its longitudinal dimension. Each sheet (11 and 16) is then subjected to heat sealing treatments in which weld lines (41) are formed in the sheets (11 and 16) thereby forming the vertically extending compartments (42) in each sheet (11 and 16). The first and second sheets (11 and 16) are then superimposed one over the other and mutually respective pairs of additional welded lines (40) are formed so as to seal or weld the double layers of the two sheets (11 and 16) together at spaced positions along the longitudinal length of the superimposed sheets (11 and 16). Each of the weldlines (40) of mutually respective pairs thereof are closely spaced, side-by-side of each other. The respective pairs of weld lines (40) are spaced from other pairs such that a plurality of compartments (42) are included in each of the sheets (11 and 16) between the pairs of weld lines (40). The sheets (11 and 16) are cut transversely of their longitudinal dimension between each of the weld lines (40) in the respective pair of weld lines (40) to produce individual units of the unique, double walled, tubular device of the invention.

Abstract: @ A pair of optical couplers (42, 44) are arranged in series with a pair of outputs from the first optical coupler (42) supplying the pair of inputs to the second optical coupler (44). At least one of the optical fibers (12a, 12b) between the first (42) and second (44) couplers is arranged to have a variable length, said variation being at least one-half the wavelength of the light signal utilized within the system. When light is supplied to one input of the first coupler (42), this light can be switched selectively to either of the outputs of the second coupler (44) by varying the length of one of the optical fibers (12a or 12b) between the couplers. Thus, a light signal supplied to either of the inputs of the first coupler (42) can be selectively output at either of the outputs of the second coupler (44) or can be made to alternate between these outputs in accordance with the length of the intervening optical fiber (12a or 12b).

Abstract: The honing machine has a honing tool mounted on a rotating spindle which is moved axially during the honing operation. The dimensions of the workpiece are measured during the honing operation by means of a sensor. Whilst a measurement is being carried out the rate at which the workpiece is being honed, is reduced. The reduction in the rate of honing is achieved by reducing the pressure exerted on the honing tool, or by reducing the speed of rotation or reducing the linear velocity of the tool.
